In this paper we present the studies conducted on blood samples taken from Mallards (Anas platyrhynchos). Birds were captured for ringing purposes (n = 43) in two small and two big towns (including highly urbanized areas). For comparison samples of blood from birds shot on fish ponds were used (n = 26). Based on the body mass all sampled individuals can be assessed as being in good condition. Levels of cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel (Ni), lead (Pb) and zinc (Zn) in blood samples were measured with AAS. Concentrations of metals did not differ statistically between sexes and made up a following order: Fe > Zn > Cu > Cr ≈ Ni > Pb > Cd. Mallards from towns revealed lower concentrations of Zn and Cu but higher concentration of Fe. There was no difference in exposition to Pb between birds from towns and fish ponds.
本研究采集了野鸭（Anas platyrhynchos）的血液样本。这些鸟类是为了环志目的而被捕（n=43），分别来自两个小镇和两个大城市（包括高度城市化地区）。为了进行比较，还使用了来自鱼塘中射杀的鸟类的血液样本（n=26）。根据体重，所有采样个体的健康状况均良好。采用原子吸收光谱法（AAS）测量血液样本中的镉（Cd）、铬（Cr）、铜（Cu）、铁（Fe）、镍（Ni）、铅（Pb）和锌（Zn）的含量。金属浓度在性别间无统计学差异，其含量顺序为：Fe＞Zn＞Cu＞Cr≈Ni＞Pb＞Cd。来自城镇的野鸭的 Zn 和 Cu 浓度较低，但 Fe 浓度较高。城镇鸟类和鱼塘鸟类对 Pb 的暴露没有差异。
